<and, surprisingly, for a supercharged V6, I'm averaging almost 30 MPG per tank!>
Yes, we are all very surprised here since this is not possible. Hyundai never made a supercharged v6 and has a EPA highway mpg of 26 and average mpg is 21. This is the 'official' figures which is usually optimistic.
With an after market supercharger (this means full rebuild of the engine and is not for everyone) I would guess mpg would be in the 'teens'.
So I agree with the first commenter, wake up! this review is not for real.
How can a 172 hp car have '... serious performance potential'? The Tiburon is not especially fast. Acceleration 0-60 mph is 7.2 seconds and that's even manufacturers numbers. Expect about 8 sec.
To the previous commenter:
Many of the available after market superchargers for the Tiburon do NOT require a full engine rebuild. Hyundai's V6 can take about 6-8 pounds of boost, well below what several available superchargers provide, without internal work.
Also, depending on tuning, especially at low boost with stock injectors, the supercharger's impact on fuel economy shouldn't be as dramatic as you think. Perhaps it was tuned for economy, rather than power, before it was sold.
"Many of the available after market superchargers for the Tiburon do NOT require a full engine rebuild."
Is this something you've read about, or something you've actually done? Basically I don't believe you since turbo tuning any non-turbo car is pretty complex. You don't just bolt on the turbo kit.
You're saying that no modification is necessary on the short block. I don't believe you. This car would not last a month, assuming that you would be able to make it run at all. Bolting on a turbo means remapping, new injectors and usually new cat or new exhaust. That is if you're lucky. Ever done a remapping for a turbo kit? Unless you have reference values provided by the manufacturer, it's pretty difficult.
To the previous poster:
I believe that the original writer of the review stated the car had a SUPER CHARGER, yet you commented on TURBO CHARGERS. I hope you understand that these are two vastly different ways of increasing manifold pressure? Just in case you don't know, turbos use exhaust gas to spin a turbine in order to increase air pressure in the cylinders (more air means better fuel burn means more power). Turbos have a mechanical lag time. Super chargers run a screw type system that pulls air into the cylinders, colder, denser air than a turbo. Colder, denser air means a better fuel burn. Super chargers are belt driven (kinda like a fan belt) and don't suffer from mechanical lag like a turbo. Most superchargers are bolt on and can be done at home with relative ease. Not so for turbos. I know there is more to this like injector size and ecu mods, but this wasn't meant to be an exhaustive manual to performance mods!
No way man have one and it gets 32mpg.
The guy speaking on a complete engine rebuild must be thinking of running at a high PSI level. At a high level, you would need injector changes and other components changed out. At low levels, it's not needed. To get the most out of an add-on (turbo/supercharger) you should get it tuned & dyno tested at a quality shop.
